[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Referring to Figures 1-3, one embodiment of this utility model provides a conveniently installable and detachable edge protection railing, including a base plate a1. The outer sidewall of base plate a1 contacts a base plate b2. The top of base plate b2 is also equipped with a fixing block 3, a rotating block 4, and a connecting rod 5, forming the other side of the protective railing. The top of base plate b2 does not have a splicing mechanism 7. The top of base plate a1 is fixedly connected to the fixing block 3, and the surface of the fixing block 3 is rotatably connected to the rotating block 4. By rotating the rotating block 4 around the rotation center point of the fixing block 3, the connecting rod 5 can be folded, unfolded, and stored as a whole. The top of the rotating block 4... A connecting rod 5 is fixedly connected to the end. A limit component 8 is provided on the inner side wall of the rotating block 4. A protective rod 6 is inserted into the outer surface of the connecting rod 5. The protective rod 6 is composed of a set of U-shaped rods and a reinforcing rod is provided in the middle. After the rotating block 4 is unfolded on the fixed block 3, the protective rod 6 is inserted into the outside of the two sets of connecting rods 5, so that the whole can be formed into a whole guardrail. The rotating block 4 and the fixed block 3 can only rotate inward. After the protective rod 6 is inserted into the outside of the two sets of connecting rods 5, the position of the two sets of connecting rods 5 after unfolding can be fixed, so that edge protection can be provided.

[0035] Referring to Figure 4, the limiting component 8 includes an insert block 81. The outer arc surface of the fixing block 3 has a slot. The end of the insert block 81 is inserted into the inner wall of the slot of the fixing block 3. The insertion between the two can fix the position of the rotating block 4 after it rotates on the surface of the fixing block 3 and drives the connecting rod 5 to flip. This prevents the rotating block 4 and the connecting rod 5 from opening during transportation. The insert block 81 passes through and slides on the inner wall of the rotating block 4. The inner wall of the rotating block 4 has a cavity, so that the insert block 81 can only slide laterally on the inner wall of the rotating block 4. The insert block 81 is elastically connected to the inner wall of the rotating block 4 by a limiting spring 82. One end of the limiting spring 82 is fixedly connected to the surface of the insert block 81, and the other end of the limiting spring 82 is fixedly connected to the inner wall of the rotating block 4. The function of the limiting spring 82 is to automatically reset the position of the insert block 81 after it is pulled outward. The top of the base plate a1 is provided with a splicing mechanism 7.

[0036] Referring to Figures 3 and 5-6, the splicing mechanism 7 includes a rotating seat 71, which is rotatably connected to the surface of the base plate a1. A threaded block 72 is slidably connected to the inner wall of the bottom end of the handle 74. A guide block is provided on the inner side wall of the handle 74, and a groove is provided on the side wall of the top end of the threaded block 72, so that the handle 74 can drive the threaded block 72 to rotate synchronously when it rotates. The handle 74 can move upward on the outer surface of the threaded block 72. An internal threaded groove is provided on the surface of the rotating seat 71, and the threaded block 72 is threadedly connected through the inner wall of the rotating seat 71. By moving the threaded block 72 up and down on the inner wall of the rotating seat 71, the bottom end of the threaded block 72 can fit against the surface of the base plate b2 or the base plate a1. Through the interlocking force and self-locking property of the threads, the position of the rotating seat 71 when it is rotated open and when it is stored on the surface of the base plate a1 can be reinforced.

[0037] Referring to Figures 5 and 6, a handle 74 is elastically connected to the top of the outer wall of the threaded block 72 via a return spring 73. One end of the return spring 73 is fixedly connected to the top of the outer wall of the threaded block 72, and the other end is fixedly connected to the top of the inner wall of the handle 74. The function of the return spring 73 is to automatically reset the handle 74 after it is pulled upwards and the insert rod 75 moves upwards within the cavity of the threaded block 72. The top of the inner side wall of the handle 74 is fixedly connected to the insert rod 75. When the handle 74 is pulled upwards, it will cause the insert rod 75 to move upwards synchronously. The threaded block 72 has an internal cavity, through which the insert rod 75 passes and is slidably connected to the inner wall of the cavity of the threaded block 72. The base plate b2... The surface has a slot, and the bottom end of the insertion rod 75 is inserted into the inner wall of the slot. The surface of the base plate a1 is also provided with a slot corresponding to the insertion rod 75, with the rotation center axis of the rotating seat 71. The insertion of the insertion rod 75 into the base plate b2 allows for the quick splicing of two sets of guardrails. The insertion of the insertion rod 75 into the slot of the base plate a1 fixes the position of the rotating seat 71. The bottom end of the threaded block 72 contacts the upper surface of the slot of the base plate b2. The contact between the two is achieved by the thread of the threaded block 72 descending and contacting the surfaces of the slots of the base plate a1 and the base plate b2. This provides secondary reinforcement to the position after the insertion of the insertion rod 75 through the engagement and self-locking of the threads.

[0038] Working principle: When the guardrail needs to be unfolded, first pull the insert 81 outward to disengage it from the slot of the fixed block 3, and rotate the rotating block 4 so that it rotates around the rotation center point of the fixed block 3. The rotation of the rotating block 4 drives the connecting rod 5 to unfold as a whole. Since the hinge between the rotating block 4 and the fixed block 3 can only rotate inward, when the protective rod 6 is inserted into the outside of the two sets of connecting rods 5, the protective rod 6 will fix the two sets of connecting rods 5 in the unfolded position, thus forming a whole guardrail and realizing the edge protection function. When it is necessary to store the whole, the operation is reversed.

[0039] When splicing the two sets of guardrails, first rotate the rotating seat 71 to position it in a suitable splicing position, then pull the handle 74 upwards. The handle 74 drives the insertion rod 75 to move upwards simultaneously. At this time, the return spring 73 is stretched, aligning the insertion rod 75 with the slot on the surface of the base plate b2. Then release the handle 74, and the insertion rod 75 is inserted into the slot of the base plate b2 under the action of the return spring 73, achieving the initial splicing of the two sets of guardrails. Next, rotate the handle 74. Due to the connection between the handle 74 and the threaded block 72, the rotation of the handle 74 causes the threaded block 72 to descend along the inner wall of the rotating seat 71. When the bottom end of the threaded block 72 contacts the upper surface of the slot of the base plate b2, the position of the insertion rod 75 is reinforced again through the interlocking force and self-locking property of the threads, ensuring the firmness of the splicing of the two sets of guardrails.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
